MiR-3606-3p Inhibits Systemic Sclerosis through Targeting TGF-β Receptor II
Background/Purpose: Though transforming growth factor-b (TGF-b) plays a fundamental role in the pathogenesis of SSc, the mechanism by which TGF-b signaling acts in SSc remains…Abstract Number: 1714 • 2017 ACR/ARHP Annual Meeting
Inhibition of Hedgehog Acyltransferase Alleviates the Profibrotic Effects of Transforming Growth Factor β in Systemic Sclerosis
Background/Purpose: Hedgehog acyltransferase (Hhat) catalyzes the attachment of the fatty acid palmitate onto Sonic Hedgehog (Shh), a modification essential for Shh signaling activity. Palmitoylation of…Abstract Number: 1924 • 2017 ACR/ARHP Annual Meeting

Background/Purpose: The Retinoic-acid related Orphan Receptor-alpha (RORα) is a member of the nuclear receptor superfamily and a ligand-dependent transcription factor implicated in a wide range…Abstract Number: 1925 • 2017 ACR/ARHP Annual Meeting
TGFβ Promotes Fibrosis By MYST1-Dependent Epigenetic Regulation of Autophagy
Background/Purpose: Autophagy (Atg) is catabolic process allowing cells to degrade unnecessary or dysfunctional cellular organelles. Aberrant activation of Atg has been implicated into the pathogenesis…Abstract Number: 2928 • 2017 ACR/ARHP Annual Meeting
STAT3 As an Important Integrator of Profibrotic Pathways in Systemic Sclerosis
Background/Purpose: Signal transducer and activator of transcription 3 (STAT3) is a transcription factor that regulates key cellular processes such as proliferation, apoptosis, invasion, angiogenesis, metastasis…Abstract Number: 2929 • 2017 ACR/ARHP Annual Meeting
WNT5A Promotes Tissue Fibrosis By Wnt/PCP-Dependent Activation of Latent TGF-β
Background/Purpose: Canonical Wnt/β-catenin signaling has emerged as a core pathway of fibrosis. They role of non-canonical Wnt signaling, however, has not been systematically studied. In…Abstract Number: 1010 • 2016 ACR/ARHP Annual Meeting
Elucidating the Activation Profile of Systemic Sclerosis Macrophages
Background/Purpose: Genome-wide gene expression studies implicate macrophages (MØs) as mediators of fibrosis in systemic sclerosis (SSc) and our data indicate that MØs constitute the dominant…Abstract Number: 1846 • 2016 ACR/ARHP Annual Meeting
Cutaneous and Visceral Fibrosis Induced By Endothelial Cell-Specific Constitutive Activation of TGF-β1 Signaling in Mice
Background/Purpose: Microvascular damage is an early event in Systemic Sclerosis (SSc) pathogenesis and may represent the initiating stimulus for the subsequent establishment and progression of…Abstract Number: 1922 • 2015 ACR/ARHP Annual Meeting
Peripheral B Lymphocytes Secrete Both Interleukin 6 and Transforming Growth Factor-Beta and Potentiate Fibroblast Activation in Systemic Sclerosis
Background/Purpose: Systemic sclerosis (SSc) is a rare connective tissue disease characterized by fibroblasts activation, increased extra-cellular matrix synthesis associated with autoimmunity. However, the potential role…Abstract Number: 2152 • 2015 ACR/ARHP Annual Meeting
Long Noncoding H19X Is a Key Mediator of Tgf-Beta Induced Pro-Fibrotic Effects in the Pathogenesis of Systemic Sclerosis and Other Fibrotic Diseases
Background/Purpose: Long noncoding RNAs (LncRNAs) are emerging as a novel class of noncoding transcripts involved in the regulation of gene expression. So far, for only…Abstract Number: 2154 • 2015 ACR/ARHP Annual Meeting
Inhibition of Gli Ameliorates the Pro-Fibrotic Effects of Transforming Growth Factor-β in Systemic Sclerosis
Background/Purpose: Hedgehog signaling plays a critical role in the pathogenesis of fibrosis in Systemic sclerosis (SSc). Besides canonical hedgehog signaling with Smoothened (Smo)-dependent activation of…Abstract Number: 1727 • 2014 ACR/ARHP Annual Meeting
Poly(ADP-ribose) Polymerase-1 (PARP-1) Suppresses the Profibrotic Effects of Transforming Growth Factor â in Systemic Sclerosis
Background/Purpose The enzyme poly(ADP-ribose) polymerase-1 (PARP-1) transfers negatively charged ADP-ribose units from the donor β-NAD onto various substrate proteins either as mono- or oligomeric moieties…Abstract Number: 968 • 2014 ACR/ARHP Annual Meeting
Priming of WNT Signalling during Fibrosis Is Mediated By TGF-β Induced Axin-2 Downregulation
Background/Purpose Systemic Sclerosis (SSc) is characterized by autoimmune activation, vasculopathy and tissue fibrosis. Recently, activation of the Wnt/β-catenin signaling pathway in SSc fibroblasts has been…Abstract Number: 768 • 2014 ACR/ARHP Annual Meeting
Transforming Growth Factor Beta Induces anti Angio and Vasculo-Genesis Phenotype in Dermal Fibroblasts through Secretion of Pigment Epithelium Derived Factor
Background/Purpose: Systemic Sclerosis (SSc) is an autoimmune disorder characterized by tissue fibrosis and vasculopathy. A proteomic analysis of the secretome of SSc dermal fibroblasts (SSc-FBs)…Abstract Number: 2560 • 2013 ACR/ARHP Annual Meeting
Analysis Of Global Gene Expression Of Pulmonary Endothelial Cells From Caveolin-1 Knock-Out Mice
Background/Purpose: Caveolin-1 (Cav-1) deficiency has recently been shown to participate in the pathogenesis of tissue fibrosis in Systemic Sclerosis (SSc). Although the mechanisms involved have…
